Jeroen contributed to several Grafana repositories by delivering features that improved security, automation, and metadata management. In grafana/crossplane-provider-grafana, he upgraded the Terraform provider and refactored credential handling to use secret references, enhancing security and maintainability using Go and Terraform. For grafana/shared-workflows, he developed a GitHub Actions workflow in Shell and YAML to install and cache the Jrsonnet CLI, optimizing CI build efficiency. Jeroen also clarified Grafonnet’s status in grafana/grafana through documentation updates, and enriched Backstage catalog metadata for grafana/grafanactl and grafana-operator, supporting better tooling discovery and governance. His work demonstrated depth in CI/CD and configuration management.

For 2024-10, delivered a security-focused upgrade of Grafana Terraform provider to v3.11.0 in grafana/crossplane-provider-grafana, along with essential repository hygiene. Updated Go and golangci-lint to current versions; tightened golangci-lint configuration with targeted suppressions and a 5-minute timeout. Refactored sensitive credentials (passwords and bearer tokens) to secret references, reducing exposure and improving security posture. These changes enhance security, maintainability, and alignment with platform standards, while reducing technical debt and enabling smoother future releases.
